must be given a place in the British list, but which are in no sense 

 indigenous; it is impossible, however, to draw the line, and many 

 more of the same soit will probably be added from time to time. 



CRYPTOPHAGID^S:. 



CRYPTOPHAGUS, Herbst. 

 This is one of our most difficult genera, and its composition has been 

 somewhat more complicated of late years by the discovery of fi^esh 

 species and especially by doubtful questions as to varieties. A con- 

 siderable amount of attention was given to the genus by the late Mr. 

 A. J. Chitty, whose loss both as a friend and a worker we so much 

 deplore ; had he lived he would probably have done very much more to 

 advance the knowledge of our Coleopterous fauna. As it was, however, 

 he wrote very little, and we therefore have much pleasure in including 

 his table of the genus Gryptoipliagus in this work, as it appears to us to 

 be the best yet published (Ent. Mo. Mag. xliii. (2 Ser. xviii, ), 1907, 165). 

 The position of the six species now added to our list is indicated under 

 their descriptions, but they are not included in this table, as this 

 would have necessitated a good deal of alteration of the whole in one 

 or two cases. 



I. Elytra with the pubescence entirely de- 

 cumbent, without longer outstanding hairs, 

 i. Eyes with tolerably tine facets. Antennte 

 stoutei', the seventh joint not or hardly 

 longer than broad. 



1. The thickened part of the anterior 

 angles of the thorax (callosities) occupy- 

 ing a fourth or fifth of the sides. 

 A. The lateral tootli of the tliorax in or 

 near the middle of the side. 



a. Antennte with a two- jointed club 



b. Antennae with a three-jointed club. 



PUBESCEXS, Sturm. 



a*. Elytra closely but not sti'ongly 

 punctured, punctuation almost the 

 same at apex as at base . . , validus, Kraatz. 



b*. Elytra becoming much more finely 

 punctured at apex, 

 af. Thorax almost as long as broad, 

 with strongly thickened anterior 

 angles, and the sides almost straight 

 with an obsolete middle tooth . fumatus, Marsh. 



bf. Thorax strongly transverse, with 

 less strongly thickened anterior 

 angles and a distinct middle tooth.
